Calculate the factor of safety against uplift. If the weight of the culvert plus the soil above it doesn't exceed the upward buoyant force by at least 1.2 to 1.5, you must increase the thickness of the bottom slab or add "toe" extensions to catch more soil weight. 2. Step-by-Step Design Calculation Process A common "fix" for overestimated stresses is correcting the
): For precast boxes, minimum thickness is typically 6 inches (150 mm). For cast-in-place, a minimum of 8 inches (200 mm) is standard. An empirical starting point is box culvert design calculations pdf fix
